    Online Trowel Fitting Guide The Wagman online fitting guide will help you easily see all of the trowel blades and pans that fit your machine. Choose the make and model of your equipment for a list of what fits your trowel. Visit www.WagmanMetal.com for the interactive fitting guide. 50 Years of Excellence Since 1963 Wagman Metal Products, Inc., has been a leading supplier of power trowel replacement blades and floating pans in the concrete industry. We want to thank our dealers and customers for their continued support, helping to make Wagman Metal Products successful. We are truly a family business that started when my grandfather George F. Wagman, Sr., and my father George F. Wagman, Jr., began production and distribution of a variety of blades to fit many brands of power trowels. Today, Wagman manufactures over 350 different blades to fit the trowels of over 40 companies. In 1980 I started working on our factory floor, performing a variety of jobs in order to learn all the aspects of the manufacturing process. My experience over the years helps ensure that all the products we manufacture meet my tough standards for quality and value. If it's got my name on it, you know you can count on it! Wagman's experience and innovation have helped pioneer the development of heavy-duty blades to cope with the stresses of the new generation of heavy riding trowels. More recently Wagman has perfected the design of the plastic trowel blade, engineered to provide burnish free finishing and unparalleled blade life.

  • The Mix Pouring – Placement – Finishing
    We work with existing concrete surfaces to protect and enhance the surface. The correct placement of the concrete slab is of extreme importance for us to provide our client with a great finished surface. The following are guidelines to pouring new concrete for a Dancer Concrete Design installed floor. Finishing procedures should be consistent. THE MIX - To help control moisture migration and vapor emission problems on interior concrete floors, a proper commercially specified vapor barrier must be placed before the concrete is poured. This is a standard for all warranty claims. - A rich Portland cement content is integral for good stain reaction. A five or six bag concrete mix is ideal. This is enough cement for thorough reaction and produces a floor that will be around 4000 psi. - When pouring in colder weather or needing a fast setting, only a non-chloride accelerator should be used. Calcium accelerators should not be used as this can affect the stain’s color. - Pozzolans, or cement replacements, may also affect the ability to stain the concrete. Pozzolan load should be under 10% of total cement content. - An additive to remove moisture in cured concrete such as “Barrier One” or “Concure” has shown no adverse effects on floors that will be polished or epoxy-coated. Any warranties or claims resulting from moisture would be carried by the manufacture of the admixture. - If the concrete mix will include fiber reinforcement a torch may be needed to burn the fibers at the surface as a part of the polishing process. POURING – PLACEMENT – FINISHING - Concrete is to be placed, floated and smoothed per ACI guidelines.
